摘要壽山石是我國最負盛名的圖章石。其礦物成分,最早人們認爲是葉蠟石,近年來認爲主要是迪開石、珍珠石。作者在壽山村的野外工作基礎上,應用X射線衍射、紅外光譜、化學全分析和電子順磁共振等方法,重點對産於壽山溪周圍的壽山石進行了礦物岩石學方面的研究。X射線衍射和紅外光譜證實,壽山溪南側和北側的壽山石均是以迪開石等高嶺石族礦物爲主,而西側的旗山則是以葉石爲主。研究表明,壽山石的外觀特征與迪開石的有序度密切有關,透明度越高、質地越好,有序度越高。

Shoushan stone, the most famous agalmatolite in China, occurs around Shoushan Village near Fuzhou, Fujian Province. People once considered shoushan stone to be made of pyrophyllite. Recently, many detailed studies about shoushan stone show that shoushan stone is composed of dickite and nacrite instead of pyrophyllite. Based on field investigation and XRD, IR, EPR and chemical analysis, the authors made mineralogical and petrographical studies in such aspacts as the mineral composition and the relationship between outh character and inner structure of shoushan stone near the Shoushan River. XRD and IR studies show that shoushan stone on the northern and southern sides of Shoushan River is composed of kaolin minerals such as dickite and nacrite, while shoushan stone on the western side of Shoushan River is composed of pyrophyllite. This suggests that mineral constituents of shoushan stone are different in different places. Furthermore, the transparency of shoushan stone is closely related to the degree of order of dickite: the higher the degree of order of dickite, the higher the transparency and the quality. Chemical analysis shows that the chemical composition of shoushan stone is similar to that of dickite, and the existence of Fe(superscript 3+) in shoushan stone is responsible for its color. EPR studies of shoushan stone also prove the existence of Fe(superscript 3+) in its crystal lattice, and demonstrate that the content of Fe(superscript 3+) in the red part of shoushan stone is higher than that in white part.
